Thе academic subject ‘Theory of musical content’ is a practical adaptation of scientific ideas that are being developed by a branch of musicology, which was formed in research by Boris Asafiev, Vyacheslav Medushevsky, Valentina Kholopova and others. It has been directing the attention of the learners to the ‘musical intonation’, the ‘musical imagery’, the ‘musical drama’, the artistic ‘theme’ and the ‘idea’ of the piece of music, the ‘program foundation’, and to the question of the author’s ‘self-expression’, intertextual connections between artistic works, and other phenomena that determine the essence of music. The years of practice show that the author’s course ‘Theory of musical content’ equips students with knowledge about the most important aspects of music, experience of its analysis and the need for thoughtful and professional seriously to refer to music. Thus, it effectively promotes formation the personality of musician.
